IMPROVEMENT lN HVDRANTS.

Specification forming part of Letters Patent No. 194,037, dated August14, 1877; application filed July 6, 1877.

To all whom it may concern Be it known that I, EKINS HAND, of the cityof Rochester, in thecounty of Mon-roe and State of New York, haveinvented a certain new and useful Improvcmentin Hydrants and I'do herebydeclare that the following is a full, clear, and exact description ofthe constructionand operation of the same, reference being had to theaccompanying drawings, in which Figure 1 is central vertical section.Fig. 2 is a top view. Fig. 3 is a cross-section in line 0: as, Fig. 1.Figs. 4, 5, 6, 7, and 8 are detail views.

My improvement relates to the means for controllingand operating thevalves for letting on and cutting ofi' the flow of water to the nozzles;also, to the means for letting on and cutting oft the flow of water fromthe main to the hydrant; and, furthermore, in the means for dischargingthedead water from the hydrant to the sewer after the flow from the mainis stopped.

A is the body or barrel of the hydrant, which is of ordinary form. B isa section which screws into the lower end of the barrel, and forms acontinuation of the same. This section connects with the main by alateral branch, (3. D is an elbow at the extreme bottom of the hydrant,which connects with a sewer or other discharge. E is ashortcylinder,which screws into the top of the barrel; and F is an open-toppedreceptacle or box on top of the hydrant, which has a hinged cover, a,secured by a clasp, which is locked when the hydrant is not in use. Thecylinder E has the ordinary nozzles bb b for the attachment of hose, andthese nozzles are covered by screw-caps, as usual. A diaphragm, o, isleft between the cylinder E and box F, and the box is attached to thisdiaphragm by means of lugs d d d, Fig. 2, through which pass screws, bywhich means the box is easily removed. B is a cylindrical extension ofthe section B, which is of somewhat smaller diameter, and projects upsome distance in the bottom of the barrel, as shown in Fig. 1. In thisprojecting portion are out two spiral slots, ff, Figs. 4 and 5, whichstart centrally opposite each other at the top, and extend down in aninclined direction till they reach the bottom of said projection.lindrical valve, which fits in the section B and its extension B. It isopen at the top, but has a check-valve at the bottom. Its exterior iscovered by leather g,.or equivalent packing,

which is close fitting to the surface in which it rests. It has in oneside and near the bottom a port, h, which, when in coincidence with thebranch 0, admits the water from the main into the valve, and thence upthrough its open top into the body of the hydrant. It also has at thetop two inclined lugs, i t, Figs. 4 and 5, which rest in the inclinedslots f f, and, as the valve is raised or lowered, the lugs travel inthe slots, and cause the valve to turn partially around; At the top ofthe valve is an arched hearing, it, having a female thread, into whichscrews the spindle H. The spindle passes up through a packing-box in thedia-, phragm 0, consisting of a socket, j, and a hol-. low screw, 1,which inclose a head, m, of the spindle, and the spindle above the screwis formed with a square head, it, for the fitting of a wrench, by whichit is turned.

It will be seen that. when the spindle is turned it will move the valveG endwise up or down, and will, at the same time, impart to it a turningmotion by reason of the lugs t 'i traveling in the inclined slots f f,as before described. Therefore the port h, in moving over or away fromthe openingof the main, will do so in an angular direction, and veryslowly, preventing sudden shock of the water, and, also obviating thelengthening of the hydrant,

which is necessary where a vertical movement alone is produced.

K is a waste-valve in the bottom of the valve Gr. It is composed of twostems, o o, with a central disk, 1), Figs. 7 and 8. The lower stemprojects through a hole in the bottom of the main valve, while the upperone rests in an arched bearing, q, whose base 1* is a separate disk,which rests loosely in the bottom of the cylinder, and incloses-the head1). This allows the parts to be removed readily, and also keeps thewaste-valve in proper position. 8 is a cross-bar in the elbow D, locatedsome little distance below the lower end of the waste-valve.

G is a hollow cy-.

When the valveG -is elevatedsoias tobring' theipor't in "line with the;opening of the main, the waste-valve will fall to place, and serve as acheck to prevent the water passing downward; but when valve G is turneddown to cut offihe water, then the waste-valve will,

strike the-crossbar syar'id be' opened to let off the waste waterliinthebody offilthei-hy drant into the elbow D, and thence into the seweror other discharge. It does not strike the, cross-bar till the flowfrornthe main-is fully cut oft.

L L L are segments which form valves to' the nozzles If-Ir b. Theyare-formed from'a' thin cylinder of metal, which is first fittedaccurately to the interior of the cylinder E by being ground in, andthen cut into sections of considerable length to cover the' o-pening ofthe nozzles. Thesesections' im-ov'e vertically.

Theyhavelugse e e, Figs. 3 and '6, throughwhich passscrews tt t,-- whichare left threaded, and pass up through the diaphragm 0, havingshoulders-wuabove and below the diaphragm to prevent erid movement,- andbein g squared at the top, as shown *at "0) v, for the-application o'fa'wrench by whichthey-are turned. The segments are guid edin their up-and'dow-n movement by scre-ws'w w, Fig. 6, which fit in slotswm,=' and -maybe tightened u-p "at any time -to -keep the-valves tight. The use ofthescre-ws t' t insures the-slow movement of theof bur'sti-n'gi the hoseby-' suddenj sh ock of the water. O'ne special' advantage of'this formof 'the valves' is that, formingsimply rims fitting 'the' cylinder, theyare very thin, and occupy "but 5 little -space,+ enabling 'thewaterchamber toibem adesma-l-l; an'd yet insuring 1 suflicientpassagefor the water to feedany desired number of nozzles.

The top of the elbow D, just below the waste-valve, is made beveled, asshown, to facilitate discharge of the water.
